Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517466, here are decompositions:

53 + 31517413 = 31517466
59 + 31517407 = 31517466
67 + 31517399 = 31517466
73 + 31517393 = 31517466
193 + 31517273 = 31517466
199 + 31517267 = 31517466
223 + 31517243 = 31517466
269 + 31517197 = 31517466

Showing the first eight; more decompositions exist.
